I would take this offline right away:

  system("ls -l /");

You can safely use that as the Ruby is run in a limited contained env. Feel free to run `rm -rf` too

I don't think you're going to be happy when somebody uses you to launch a DDOS:

  system("ping -c 2 8.8.8.8");

  PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
  64 bytes from 8.8.8.8: icmp_req=1 ttl=55 time=1.98 ms
  64 bytes from 8.8.8.8: icmp_req=2 ttl=55 time=1.75 ms

Looks nice, but could do with a max execution time or some other limiter.

  loop do
    puts 1
  done
